Aimed at better understanding of the fructification and fruit yield in Xanthoceras sorbifolia for large scale development of bio-energy from it in Northern China, its fructification, yield and production costs were investigated and assessed in Wengniute of Inner Mongolia, Tongliao of Jilin and other regions.Assessments of impact of ages and stand density on unit area seed production, kernel yield, oil content and output value were applied for X.sorbifolia stand under following approach: afforestation with super clones and intensive cultivations.The results showed that lack of high quality seeds and extensive cultivation caused low fruit yield of X.sorbifolia.The highest fruit yield, oil production, yield value and benefits per unit area were predicted based on investigation of application of the improved varieties and intensive cultivation and fructification of existing X.sorbifolia at various ages from different regions.%针对目前我国北方各地大规模开展生物柴油树种文冠果能源林基地建设,却又不了解文冠果结实和产量情况的现状,分别在内蒙古翁牛特旗、吉林通辽等地对不同树龄文冠果单株结实情况或产量及生产成本进行了调查,并对良种化和集约经营条件下不同树龄和栽植密度的文冠果的单位面积种子产量、种仁产量、产油量、产值进行了测定与评估.结果表明:口前各地文冠果单株产量和单位面积产量均相对低下,不足以调动人们种植文冠果的积极性,而文冠果产量低下的主要原因是缺少良种和经营粗放.文中在调查各地不同树龄文冠果的结实情况的基础上,预测了在实现良种化和集约经营的前提下文冠果的单位面积产量、产油量、产值及经济效益.
